My background: I am getting a software engineer job where ML is part of the recommended skillset. I want to learn ML to help the product or company. How should I start?

I studied Economics and had some statistics knowledge. I also had several years of experience as a data analyst.

Every day I have about 1~1.5 hours. My new job starts in 1.5 months.

What is the best action I should take?

BTW, I don't mind paying for good content.

What are the best open source TypeScript frontend and backend real world projects I can learn from?

I am a self-taught web developers and I haven't worked for any good companies. There are no seniors reviewing my code.

My code quality can be improved but I don't know how. Maybe reading some good codebase is a way out.

I use React in frontend and express in Backend. Do you know any good OSS projects that use those stacks?

Maybe I should read popular OSS frameworks instead of web app's source code? I am thinking of changing my job, so reading real web app's source code might be more relavant.

I am very thankful for any advices. And Happy New Year!

Hi HN. I asked a question here before. [my app is slow. What do I do now?](https://news.ycombinator.com/item?id=29700098). HN users kindly instructed me to record logs about my api request as a starting point. I have done accordingly and found some slow api requests and fix them.

But recording api request and analysing them with custom python code is not as interesting as creating features for my app.

Are there any service that I can use to simplify this task?

I've used Mixpanel to collect and analyse my user behaviours. So far it is working great.

I'm thinking of using Mixpanel to collect and analyse my api request data. But I'm not sure Mixpanel is good fit for this task. (I'm not an expert in Mixpanel though).

Have you used any service to do such task? I would be happy to pay for the service.

Thanks :)

I built a web app. To be precise, it is a web app inside Wechat ( I am in China).

Every day there is around 200 users, and it generates me some ramen profit.

Users report that my web app is sometimes slow.

I know that there are many plausible causes. But before I jump into the rabbit hole, I want to ask for your kind advice.

What is your mental framework to deal with such a problem?

FYI, my app:

- is built with NodeJS

- ran on a cloud server with 2 core CPU, 2G Ram, and 1M bandwidth

- is a CRUD app

I have learned about building apps from the web, mostly from Udemy and Youtube. Someone has told me to not worry about performance. `Make it work, then make it better`.

Now that I have learned how to make it work, how can I learn how to make it better? Do you have any links or materials to share?

Thanks a lot.

Hello, I am working on my startup at home. I have a child who is 20 months old. He clearly doesn't understand the fact that his father is working. Besides, he is just too cute to ignore.

I wonder anyone has similar experience. How do you deal with it?

FYI, there is no cheap coworking place in my city.
